Serious scholars have examined what happens when we change the number of H1-B visas issued.

Cities that get more H1-B immigrants subsequently see the wages of natives *rise* substantially.

Skilled immigrants bring new ideas, fill labor shortages and make us all more productive.

Just added my signature to the letter.

This is a no brainer.

It’s wild we’re having a conversation about US central bank independence in 2025. But here we are.

Please read and consider adding your signature.

Is it more effective if the experts cited respond jointly? separately? Is it better to respond by chapter? Who is considered to have a more "legitimacy" in submitting comments? How are comments weighted in the review process? Is there evidence that the comments make a difference?

I have written about this before, when it was suggested as a possibility shortly after the inauguration. A quick summary here--in short, there's little clever or thoughtful about it, though there is some legal strategy at work, however cynical.

Our paper is officially out 🎉

We argue that climate clubs show promise:

- A climate club with coordinated penalties could curb 68% of excess emissions from free-riding

-Unilateral carbon tariffs? Not nearly as effective

We study how trade policy can reduce global emissions. Unilateral carbon border taxes have limited efficacy at cutting foreign emissions. By contrast, coordinated trade penalties under a climate club prove highly effective. buff.ly/NEE3Uy8

I'd love to fund studies of interventions that reduce real-time pollution exposure, in the US, on outcomes related to violence and criminal behavior.

(There is strong evidence that such exposure increases violence in real time; the next question is how much interventions can mitigate this effect.)

Yeah makes sense… you may also have holidays in Dec that could alter driving and traffic.
arielob.bsky.social
Thanks for sharing. Any ideas why December is lower than Jan and Feb which are colder months?

Telling prospective PhD students that they should not worry about stating their research interests on their statement was not in my bingo card for 2025.

Who, us, delete #climate info?

USDA has agreed to restore climate change-related webpages to its websites after it was sued over their deletions by the Northeast Organic Farming Association of NY and others,

Facing lawsuit, USDA says it will restore climate change-related webpages
The U.S. Department of Agriculture has agreed to restore webpages related to climate change after it was sued earlier this year over the deletions.

Don’t know. Note the report cannot be “cancelled” by the executive but the law does not explicitly require external experts or give details about their selection

As I understand it the executive can fire us w/o reason (we’re not paid btw) but they have to produce the NCA report at least every 4 yrs

It was an honor for me to serve as one of the authors of the economics chapter alongside a distinguished and professional group of experts.

I cannot overstate how serious and non partisan this group was.

We received the dismissal emails yesterday.

This report is congressionally mandated and aims to inform the US people about the impacts of climate change on the nation and what to do about it.

Federally funded R&D (not all of which is spent at universities) as a fraction of GDP is as low as it's been since we started tracking.

Which is a different way of looking at it than "line go up." 4/x ncses.nsf.gov/pubs/nsf2332...
Line graph of the ratio of US R&D spending from various sources to GDP, 1953-2021. The federal percent ranges from about 0.6% of GDP to 1.8%, with the peak in the 1960s, and the low point at the very beginning and over the last 20 years.

There are so many ways one could provide context for this data.

For example, in the last five years universities have received 52-55% of their research funding from the federal government. That's the lowest percentage since the 1950s. 1/x ncses.nsf.gov/surveys/high...
How Universities Became So Dependent on the Federal Government
For decades, universities got billions in federal dollars for research. The relationship was mutually beneficial, until President Trump decided it wasn’t.
